<p>Quantifying various things using one's own tools and ideas is a common habit in any civilization. Ethiopia, one of the oldest civilized nations, engages in trade through a variety of channels. In Ethiopia, Tigray is one of the areas where the people use measurement to facilitate trade. There are several kinds of containers and local measuring devices that are used as quantification tools. Therefore, this study intends to investigate several traditional measurement tools and conversion methods to the metric system, as well as other fundamental mathematical activities within the framework of ethnomathematics. The methods used to collect data included document analysis, interviews, field notes, and observation. The results of this study show that different ethnomathematical ideas are used in rural areas of Tigray. According to our research, there are many mathematical activities that are deeply rooted in the local society's daily routines. These measurements are used to measure length, capacity, weight, time, area, and other quantities. In recent years, these measurements have been dominated by standard measuring instruments in many areas, but they are still used in rural areas and remain essential for local trade and construction. These practices are an input to aid the development of curricula that incorporate indigenous knowledge and help students appreciate their culture of mathematization. The study further documents how Tigrayan measurement systems embody addition, subtraction, multiplication, and fractions, offering a foundation for culturally responsive mathematics education.</p>
